Thus, when the BH singularity is fully removed and BH is evaporated, we will have very low entropy photons (due to thermal radiation of BH evaporation) while the second EH will become identical to horizon of dS universe. The above results are in complete agreement with the Conformal Cyclic Cosmology (CCC), where at the ending phase of an aeon, low entropy photons are produced which can pass through the crossover and have their trace on the next aeon [1]}, [2]}, [3]}. Meantime, it should be noticed that in such cases, the negative root \(r_3\)  of SdS solution will become identical to \(-\sqrt{\frac{\Lambda }{3}}\) . Indeed, this negative root can be considered as the dual of our original dS spacetime with the same amount of IC and entropy according to Eq.(REF ).
